President Trump responded to a New York University professor’s false tweet saying it was an example of journalistic malpractice, while calling for the U.S. to modify its libel laws to hold news media accountable.

In his tweet the president said a fake quote attributed to him by Ian Bremmer shows “what’s going on in the age of Fake News.”

“People think they can say anything and get away with it,” Trump wrote. “Really, the libel laws should be changed to hold Fake News Media accountable!”

Ian Bremmer, the president and founder of Eurasia Group and a New York University political science professor, tweeted out a fake quote attributing it to President Trump, then claimed it was “plausible” the president would say it. Later he deleted both his tweets, which you can see below:
